Tiny Ariana Cruz-Gutierrez weighed as much as three sticks of butter when she was born at just 24 weeks on March 9 at Anne Arundel Medical Center (AAMC) in Annapolis.

At exactly 12.4 ounces, Ariana was the smallest baby AAMC has ever seen when she was welcomed by her mother, Claudia Cruz, and father, Oscar Gutierrez.

Following months of care from neonatal experts and nurses, Ariana — now 4 pounds, 15 ounces — was sent home Aug. 3 after showing positive signs of development.

“She met all of the criteria that we would sort of look for, like any sucking, swallowing, breathing on her own," AAMC spokeswoman Arminta Plater, told InsideEdition.com.

"The tiniest baby ever born at AAMC went home today!" AAMC said in a celebratory Facebook post. "Special thanks to our amazing NICU team who took care of Ariana during her stay here, and her parents who were dedicated partners in her care."
